George R.R. Martin Developing New HBO Series

In this story

The Game of Thrones author is developing a new series with HBO, The Hollywood Reporter has confirmed.

The potential series is called Captain Cosmos and centers on a young science fiction writer living in 1949 at the dawn of the age of TV. The writer spends his time penning stories no one else would dare to write.

The series is in early stages of development at the network, where Martin has an overall deal. The pilot is being written by Michael Cassutt, a writer and co-executive producer on SyFy's Z Nation.

The proposed series is not expected to be a big time commitment for Martin, who announced last month that he was dialing back on appearances in order to focus on writing The Winds of Winter, the long awaited sixth installment of his Song of Ice and Fire series. The previous book, A Dance With Dragons, was published in 2011.
